Patent DE-3102700-A1 (DE)
Title: Buckle tongue for safety-belt buckles
Inventor: ERNST HANS-HELLMUT ING GRAD
IPC: A44B11/25
Filed: 1981-01-28
Abstract: The invention relates to a buckle tongue for safety-belt buckles as an important constituent in a safety-belt system. The object of buckle tongues is to constitute the releasable connecting member as a force-transmission element for a closed or open safety belt. During handling, relative movements often take place between the belt strap (10/11) and the buckle tongue (1) at the deflection point (7), thus resulting in abrasion and thus reducing the service life. In the event of an accident, the deflection point (7) is also a critical point due to the force transmission taking place at that point. An improvement in the situation is achieved by this invention in that the deflection point (7) on the upper web of the buckle tongue (1) is designed as a large-volume, virtually circular cylinder with a diameter of preferably 10 to 20 mm. Owing to the larger contact surface, a lower specific load is thus exerted on the belt strap at risk. In an advantageous embodiment, the cylinder is formed by ribs (6). <IMAGE>
